Having failed miserably to overclock this CPU on my Asrock 880GMH/U3S3 board viewtopic.php?f=28&t=62817&p=577294#p577294 I've now decided to undervolt it instead. As it will be only serving media files to a RPi sometimes, it seems to make sense to have it run at as low-power as possible when idle.

Using PhenomMSRTweaker, I've tested with it locked to 4x (800Mhz) which is the lowest multiplier available and set it to 1.0v (down from 1.1v) and that seems stable and also tested at 8x (1600Mhz) at 1.1v (down from 1.2v) and that seems OK too. I haven't properly stability tested yet though and was wondering whether tools like IntelBurnTest are still valid for testing when locked to lower frequencies or if they're only any use at full speed?

At full 2.8Ghz, what voltage am I likely to be able to lower the VID to, from the default 1.4v (1.368v Vcore) and what am I likely to be able to get down to at 800Mhz and 1600Mhz?

Is there any scope for lowering the NB VID from the default 1.175v and is that likely to confer any significant power savings or is that rather minor compared to the CPU v?
